To all whom t may conce/m.'

Be it known that l. HARVEY BRAMES, a citizen of the United States, residing at Norfolk, inthe county of Norfolk and State of Virginia, have invented certain new and useful Improvements. in Hydraulic Piling, of which the following is a specification.

My invention relates to hydraulic piling.

The object off the invention is to provide means for eflicientlysinking cement or concrete piles by the aid ofv jets of water, for foundations of buildings, bridges and the like.

Further objects and advantages will be.

more fully described herein and specifically pointed out in the claim hereunto annened recourse being had to the accompanying.

drawing forming a part of this specification in which :f

Figure 1 is a sectional view or" draulic water jet apparatus.

Figure 2 is a sectional elevation of a con crete or cement pile with my device in place therein. i i

Figure 3 is a sectional plan on the line 1-2 in Figure 1, and

Figure 4 is an elevation of one end of the connect-ing link with a. bifurcated extremity.

In the drawing like reference numerals indicate similar parts in all the several views :4-

l represents the tapering cement or reinforced concretepile which is provided with a bore or hole 2 vertically throughout its length both for lightness, strength and for the hereinafter described hydraulic cylinder to be placed therein and afterwards withdrawn at will.

In order to sink the pile by displacing the sand or earth by jets of water at high pres sure, the hydraulic cylinder 3, is lifted by a derrick or otherwise placed in the hole 2 of the pile and allowed to discharge water the pile which washes away the sand or soil and allowsthe pile to settle to its place, after which the low of water is discontinued andthe cylinder with drawn for a subsequent operation.

The hydraulic cylinder consists of a shell 3 terminating in a point 3a, at its lower end, and contains the mechanism to be hereinafter described. 4 is a sleeve having a centrally located screw thread 5 and having a portion of the same, within the cylinder or casing 3.

The upper part et of the sleeve is adapted the hyas 'at 6, Figure 1,V

.part of the cylinder 3,

which exerts a supply and forces the arms,

Serial No. 509,058.

to receive a hose 6 by which water is conveyed to the cylinder 3.

The lower part of the sleeve 4, as at 6, is providedy with a bevelled edge to act as a seat 7 for the valve 8.-

Si is a cross bar provided with lianges 10 and holding bolts 11, secured to the inner and is furnished with an orifice or bore for the slidable passage of the valve stem 12 and acts as a guide and support therefor.

Between the valve 8 and the cross bar 9 there is placed a coiled or spiral spring 13 pressure against the valve 8 to keep it fast upon its seat until overcome by the superior pressure of the water and tliifercfore closes it when the water is shut o Connectedito the valveY stem 12, by the` .yoke 14, is a link 15 which is in turn connected by another yoke 16, to the ends of the levers 17 which are normally at right angles to the axis ofthe cylinder 3, and are pivcted on the rods 19, as in Figures 1 and 3.

The levers are also bent upwards nearly at right angles but curved, as at 18, Fig! ure 1.

All the joints at the yokes are suitably fulcrunled on pins in the usual manner.

ln order that my invention may be effective, the point of the getting device should extend slightly below the point of the con` crete pile, 1, and water should flow therethrough. This object is accomplished byinsertingthe said device in the upon water immediately starts to flow through the point due tothe fact that the levers 18, are depressed by engagement with the -bore oi the pile and thereby open the valve. However, when the point is forced below the foot of the pile, the spring, 13, closes the valve, thus cutting oit' the water 18, outwardly.

his stopping ot the water flow indicates to the operator that the point has passed below the foot of the pile. Thereupon, the device is raised slightly to cause the upper portions of the arms to re-engage the walls ofthe bore of the pile andre-open the valve, where it is held in an operative position.

The bottom of the slots 20 are made slopingV so as to direct the water are also the jet orifices 22.

23 vare horizontal jets,

downwards as f (which may be arl pile, wheref tangential yflow) for the wafer and there may be any number desired alsoplaced at any angle.

25 are suitable Wire ropesby which the 5 cylinder 3 may be lifedby a, crane or other means, into the bore of the pile 1. .Ivclaim- In a device of the clase. described, the i y combination /With e j pile having aA longL l0 ytudinal bore therethrough, of a cylinder in said bore having a closed point thereon proand 24 are vertical orifices HARVEY ABRAMES.
